Abstract: 470,136. Loose-leaf binders. GILBERT, A. Aug. 5, 1936, No. 21582. [Class 146 (i)] In or for a loose-leaf binder of the kind having filing posts with sheet-securing members which screw into or on to the posts, a locking-slide is provided adapted to bridge two or more of the posts and enclose the securing members and carrying means which, when the slide is moved to locking position, engage one of the securing members and connect the slide irremovably to the posts for permanently binding the leaves. In one form, the locking- slide comprises a channel-shaped member 11, Figs. 1 and 9, with inturned edges which fit over the edges of the screw-head 9 and engage a part 10 of smaller diameter, a pivoted spring-catch or a leaf-spring 14 and a stopblock 13 being secured to the slide 11 so that when it is slid over the posts the spring 14 snaps behind one side of the head 9 and the block 13 engages the other side of the head to prevent the member being slid off. A guard tray 16, Fig. 8, is secured to the post by the perforated lug 17 before the slide 11 is placed in position and prevents access to the spring 14. Either the head 9 or the part 10 is provided with at least two parallel edges for engagement by the member 11 to prevent rotation thereof. The part 10 spaces the head 9 from the cover to afford room for the inturned edges of the member 11. The locking-slide may be formed integrally with one of the covers, Fig. 9, and in this case, holes 30 are provided in the slide 11 so that the threaded parts of the screws 8 can be inserted therethrough while the binder is being used as a temporary binder. When the screw heads are unprovided with straight edges preventing their rotation, the member 11 has a flat metal strip extending along the backs of the leaves so as to prevent the insertion of a tool for rotating and unscrewing the posts. In a modified form, Fig. 12, the locking slide is in flattened tubular form and is provided with key-hole slots 23 to receive the screw-heads 9. The ends of the slots may act as stops to take the place of the stop 13 or a projection 27 on the slide may engage the end of the cover. In a further alternative, the cover mav be provided with a stop 26 which engages one end of the slide. A slidable plate 35 is provided inside the locking slide adjacent to each spring 14 and has a hexagonal hole to receive the hexagonal screw-head. This plate closes the key-hole slot and prevents tampering. The locking-slide may be applied to a binder having two circular posts to engage each T- shaped slot in leaves normally used in thong binders, the spring 14 being adapted to engage the edge of one post of the pair and the stop 13 being adapted to engage the opposite edge of the other post.

Title: Telegraph system with correction by repetition of disturbed signals
Inventor: SILVA HERMAN DE
IPC: H04L5/22
Filed: 1961-06-16
Abstract: 940,463. Telegraphy. DE STAAT DER NEDERLANDEN, TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEURGENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. June 16, 1961 [June 28, 1960], No. 21819/61. Heading H4P. In a two-way telegraph system in which errors are corrected by repetition and in which a number of transmission channels is allocated to a larger number of terminal stations on a time allocation basis, means is provided for extending the allocation period by the period of the repetition cycle if such a cycle is in progress at the normal end of the allocation period. In the embodiment described, a 32-character allocation period and a 4-character repetition cycle are used, and there are 32 stations and 16 channels. The transmitter Z and remote receiver O, Fig. 1, contain similar equipment comprising a ring counter T32, which determines the normal allocation period, and T4, which determines the repetition period. Under normal conditions, at the end of the allocation period T32 and T4 are both at full count. T4 therefore feeds a positive voltage to diode 2 and T32 sets trigger Az to feed a positive voltage to diode 1. The repetition distributer, being inoperative, provides a like voltage to diode 3 so that when the transmitter distributer provides a positive pulse to diode 4 trigger Sz is set, which action resets Az. When set, Sz permits the station to be allotted a new channel. However, if a repetition cycle is in progress due to faulty reception, diode 3 is fed with a negative voltage and so Sz can not be set until T4 has regained a count of 4 and the repetition cycle has been completed, i.e. the allocation period is extended by 4 or a multiple of 4 characters. Re-allotment of the channels is performed by the arrangement of Fig. 4. A matrix of triggers corresponds in rows to each channel, and in columns to each station. When a station has data to transmit its corresponding contact ct is closed. Assume that contacts ct2, ct4 . . . ctn are closed (n=32). At the end of the present allocation period of any one channel, 16-stage counter K1-K16 receives a pulse so that K1 supplies an output to the first row of triggers. 32-stage counter T1-T32 is now brought into operation and pulses each column of triggers in turn until it reaches a column having a requesting station on it, in this instance column 2. The result of the three inputs to trigger T2.1 is to allocate channel 1 to station 2 and for counter K1-K16 to be stepped by one. Counter T1-T32 starts again, and this time allocates channel 2 to station 4. The process continues until all the channels have been allocated or until there are no more requesting stations. A channel can not be re-allocated if Sz is not set, i.e. if a repetition cycle is proceeding on that channel.

Abstract: 440,872. Glass manufacture. CORNING GLASS WORKS, Walnut Street, Corning, New York, U.S.A.-(Assignees of McCauley, G. V. ; 70, East 4th Street, Corning, New York, U.S.A.) Aug. 2, 1935, No. 21993. Convention date, Feb. 28. [Class 56] A method of cooling a large mass of molten glass consists in cooling it rapidly to a temperature below the softening point but above the annealing point, reheating the exposed surface of the mass to permit the exterior to yield and compensate the shrinkage of the interior, and then annealing the mass. Fig. 2 shows apparatus for casting a telescope mirror of large diameter. The apparatus consists of a heating kiln 10 which is provided with gas burners 11 and a door opening 12, and is suspended over a refractory mould 14. The bottom of the mould is provided with refractory cores 16, and electrical heating - elements 15, and thermo-couples 20, 21 project through the mould wall. The mould is supported by a screw hoist 17 on a car 18 which runs on a track 19. Fig. 3 shows an annealing kiln 22 which is suspended above the track 19. The interior of the kiln is provided with electrical heating-units 24, 25, and a large refractory mould cover 26 is movably supported within the mould. In use, the mould is preheated in the kiln 10 by the burners 11, and glass is then ladled from a melting-tank into the mould through the door 12. The glass is introduced at such a rate into the relatively cool mould that the lowermost and interior portions of the casting are cooler than the upper portion. When the mould has been filled, the glass is allowed to cool as rapidly as possible until the exposed surface has congealed and is at a temperature below the softening point but above the annealing point. The exposed surface.is then reheated rapidly to a point above the softening point to relieve internal stresses. The mould is then removed to the annealing kiln 22, and the casting is annealed, the rate of cooling being regulated by means of the heaters 15, 24, 25. The cover 26 protects the heaters 24 from the radiant heat of the glass in the mould.
